Answer:

8 vertices

Step-by-step explanation:

Use Euler's Theorem: V-E+F=2

F=12

E=18

Thus, we have:

V-18+12=2

V-18=-10

V=8

So there are 8 vertices

A cable weighing 0.6 pounds per foot is attached to a small 80-pound robot, and then the robot is lowered into a 60-foot deep we
ollegr [7]

Answer:6060 foot-pounds

Step-by-step explanation:

Given

Weight of cable(w')=0.6 pound per foot

depth of well=60 foot

weight of wrench=7 Pound

Now work done in raising monkey with wrench=w\cdot h

W_1=(80+7)\cdot 60=5220 foot-pounds

Now work done in raising rope

robot rises by climbing up the cable with one end of the cable still attached thus robot support half the weight of cable so work done

W_2==\int_{0}^{60}\frac{w'}{2}xdx

W_2=0.3\times 0.5\times  (x^2)_0^{60}

W_2=540 foot-pounds

W_{net}=5220+540=6060 foot-pounds
